How many hours of supervised work are required for each NDI technician for penetrant method?

• A. 8 hours
• B. 16 hours
• C. 20 hours
• D. 25 hours

Answer: (B)

The requirement for the number of hours of supervised work for each NDI technician specifically trained in the penetrant method is set at 16 hours. This time is essential for ensuring that technicians gain adequate hands-on experience under supervision before they can perform non-destructive testing independently. This supervised practice allows them to learn proper techniques, understand the test methods intimately, and comply with safety protocols effectively. If technicians were allowed fewer hours of supervised training, they might not develop the necessary proficiency to perform penetrant inspections safely and effectively, potentially leading to undetected flaws in materials being tested. The structured training approach aims to uphold the high standards of safety and quality in aviation maintenance operations.
